The overall model was highly significant ( R 2 = 0.641, F = 19.15, p < 0.0001).

Similarly, PAI β , although not reaching statistical significance, showed a trend for a positive relationship to WTP ( R 2 = 0.273, RMSE = 0.993, estimate = 0.161, t = 1.67, p = 0.0967), which means that stronger engagement of the left PFC in beta frequency band was related to higher WTP.
